Office Action

§112
DETAILED ACTION Notice of Pre-AIA or AIA Status The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Claim Rejections - 35 USC § 112 The following is a quotation of 35 U.S.C. 112(b): (b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention. The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph: The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention. Claim 13 is rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. Claim 13 recites the limitation "a second adhesive layer disposed on sides of the second lower wiring line" in line 2. It is unclear if the sides of the second lower wiring line are the same sides presented in claim 12. For the purpose of compact prosecution, the examiner is interpreting the sides of the second lower wiring line recited in claim 13 to be the same sides recited in claim 12. Allowable Subject Matter Claims 1-12 and 14-15 are allowed. Claim 13 would be allowable if rewritten to overcome the rejection(s) under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), 2nd paragraph, set forth in this Office action and to include all of the limitations of the base claim and any intervening claims. The following is an examiner’s statement of reasons for allowance: As to Claim 1, no art found by the examiner, either alone or in combination, teaches or renders obvious the limitation of a dielectric layer (separate from an adhesive layer) being located around a lower wiring line, and wherein the adhesive layer is between the dielectric layer and the lower wiring line. While previously cited art could, in principle contain an additional dielectric layer, no rationale for doing so has been identified by the examiner. Claims 2-10 are allowable due to their dependence on allowable claim 1. As to Claim 11, no art found by the examiner, either alone or in combination, teaches or renders obvious those analogous limitations to those in claim 1. Claims 12 and 14-15 are allowable due to their dependence on allowable claim 11. Conclusion Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a). A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action.
